Hiding it is good, but do be careful how well you hide it...
It needs to be near to a reasonable TV/monitor, especially if you go for the 4K one, as you may want to be able to look closely at the images. Obviously the bigger and better the TV/monitor, the more cameras you can clearly monitor at once as well. With our 50" TV, you can clearly watch all 8 at the same time, but when I was setting it up on the little 19", you could only really watch one at a time, as the image got too small on the others. On Playback, you can select up to 4 cameras at a time to watch, which can be handy when trying to find the actual time an event occurred.
You will need to spend some time sitting in front of it when you set it up, learn how to use it, and again when actually looking for something, so a comfy seated position is best.
It wants to be somewhere where the Temperature does not get too extreme. Lofts can get very hot in the summer, and that will kill the Hard Disk Drive.
When I used to install voice recording systems, one of the biggest issues was because they are a passive device, you tend to only go to use them when you actually need to find a recording, which in the ideal world is hardly ever. This means that if something has gone wrong with the equipment, you won't notice until it is too late. A lot of systems send Emails when things are not right, but of course, if the whole system dies, it can't send an email, which by default means every thing is OK. It needs to be somewhere where you will look at it every so often, ideally daily, to make sure the lights are on, and there are no beeps etc.
Spiders are obsessed with the cameras, and again, a quick glance soon tells you is one has decided to live on the lens... Login in remotely is good, but it's not as easy as just switching the TV to one of the HDMI inputs for a quick look. My Neighbour actually uses theirs to decide if they will answer the door or not.
I know a lot of these things can be done remotely, but it is much slower, it takes time to log in, then any recordings you want to view will need to be downloaded over the Net, which does take time, especially if you are viewing more than one camera's recordings, so I find that for ease, I go back to the NVR when I am really searching for something.
Just my 2cents worth...:doh:lol
